drm/vesadrm: Avoid NULL-ptr deref in vesadrm_pmi_cmap_write()

2025-06-27T14:00:49Z

Only set PMI fields if the screen_info's Vesa PM segment has been set. Vesa PMI is the power-management interface. It also provides means to set the color palette. The interface is optional, so not all VESA graphics cards support it. Print vesafb's warning [1] if the hardware palette cannot be set at all. If unsupported the field PrimaryPalette in struct vesadrm.pmi is NULL, which results in a segmentation fault. Happens with qemu's Cirrus emulation.

drm/vesadrm: Use helpers for programming gamma ramps

2025-05-26T07:19:25Z

Replace vesadrm's code for programming the hardware gamma LUT with DRM helpers. Either load a provided gamma ramp or program a default. Set the individual entries with a callback. Each gamma value is given as 3 individual 16-bit values for red, green and blue. The driver reduces them to 8 bit to make them fit into hardware registers.

drm/sysfb: Share helpers for screen_info validation

2025-04-14T08:16:14Z

Share efidrm's and vesadrm's validation of struct screen_info in shared helpers. Update the drivers. Most validation helpers test individual values against limits and can be shared as they are. For color formats, a common helper looks up the correct DRM format info from a driver-provided list of color formats. These screen_info helpers are only available if CONFIG_SCREEN_INFO has been selected, as done by efidrm and vesadrm.
